Question 1: A floating static route is configured with a greater administrative distance to provide a backup route to a route learned from a dynamic routing protocol.
A. Ano
B. Ne
Explanation: Floating static routes are backup routes that are placed into the routing table if a primary route is lost, and they are configured with a greater administrative distance to achieve this.
Question 2: What IPv6 address and prefix length is used when configuring an IPv6 default static route?
A. ::/0
B. FF02::1/8
C. 0.0.0.0/0
D. ::1/128
Explanation: The IPv6 address and prefix for a default static route is ::/0. This represents all zeros in the address and a prefix length of zero.
Question 3: HSRP allows multiple active routers to simultaneously forward packets for a single HSRP group.
A. Ano
B. Ne
Explanation: In an HSRP group, one router is elected as the active device to forward packets while another acts as the standby router. The standby router assumes packet-forwarding responsibility only if the active router fails, ensuring high network availability.
Question 4: Two devices, PC-A and PC-B, are connected to different switches and are both assigned to VLAN 60. If PC-A is unable to communicate with PC-B, and their traffic must pass over a trunk link, what is a likely cause related to the trunk's configuration?
A. The trunk has been configured with the switchport nonegotiate command.
B. The VLAN 60 is not in the list of allowed VLANs on the trunk.
C. The native VLAN should be VLAN 60.
D. The native VLAN is being pruned from the link.
Explanation: When devices on different switches need to communicate within the same VLAN, their traffic must traverse a trunk link. Trunks can be configured to only allow specific VLANs. If the VLAN associated with the devices (VLAN 60 in this case) is not in the list of allowed VLANs on the trunk, communication between them will fail.
Question 5: Replacing at least half of the switches with hubs is an effective strategy to reduce the size of the broadcast domain.
A. Ano
B. Ne
Explanation: The study materials suggest that segmenting the LAN into smaller LANs and routing between them, which creates two smaller broadcast domains, is the method to contain broadcasts, as a broadcast will only be sent to devices on the same Ethernet LAN.
